As Arthur Departs, Heat and Humidity Build East, Then Storms

In the wake of Hurricane Arthur, beautiful weather will close out the weekend in much of the eastern U.S.

In places ravaged by the storm, such as the Outer Banks of North Carolina and eastern New England, dry, sunny and relatively cool weather will prevail to close the long holiday weekend, aiding in cleanup efforts and other outdoor plans.

The stretch of comfortable conditions are due to a zone of high pressure that will slide across the mid-Atlantic through Sunday.

As this area of high pressure moves into the Atlantic on Monday, a cool, northwesterly wind will cease and swing around to the southwest. As a result, humidity levels will rise for the start of the week.

A return to typical midsummer temperatures is expected through at least Wednesday in the eastern third of the country. The core of the heat should be centered across the Carolinas where some spots may touch the century mark come Tuesday and Wednesday.

In the I-95 corridor of the Northeast, thermometers should make another run at the 90-degree mark for the second consecutive week. New York City, Philadelphia and Washington, D.C., could have three straight days of 90 degrees from Monday through Wednesday.

In addition to the 90-degree weather, dew points in the 60s to near 70 will make for uncomfortable outdoor conditions. Those exercising or spending time outside are encouraged to hydrate frequently and find shade when possible.

A cold front lurking to the west will sag southeastward through the first half of the week. This front will serve as a focal point for heavy thunderstorms.

The Great Lakes are forecast to get thunderstorms Sunday, some of which could be severe. On Monday, the Ohio Valley should receive the brunt of the stormy weather while the focus on Tuesday and Wednesday will shift into the Northeast and mid-Atlantic.

By the end of next week, signs point toward more comfortable conditions with lower humidity returning to the Northeast. Stormy conditions may continue in the Carolinas as the front lingers across the region.
